The Effectiveness Of Computer Assisted Instruction Of Chapter I Students In Secondary Schools, Robert Lloyd Davidson

Doctoral Dissertations

The major purpose of this study was to determine the effectiveness of computer assisted instruction in the mathematics classroom. Mathematics achievement scores of Chapter I students receiving only traditional instruction were compared to mathematics achievement scored of Chapter I students using computer assisted instruction. Chapter I students from grades 9, 10, 11, and 12 at Fulton High School, Knoxville, Tennessee, were chosen. Form J of the Metropolitan Instructional Mathematics Test was administered to establish the initial level of students' mathematical achievement. Thirty-six students were in the control group and 18 were in the experimental group. The 18 students in the …

The Incorporation Of Sleep And Dream Research Into The Choreography Of For A Brief Moment . . . , Melinda C. Chesney

Masters Theses

The purpose of this thesis was to design a movement concept based upon specific aspects of sleep and dream theory. First, a review of literature explored various brain wave patterns occurring during sleep and the dream process. Next, dream documentations were used to examine the more common images and symbolisms of dreams. These brain wave patterns and dream images were then utilized in the development of movement sequences and concepts for the choreographic work For a brief moment . . .. The culmination of this choreographic thesis was the presentation of For a brief moment . . . at the …

Modulation Of Drug Metabolism By Food Restiction, Paul Kupen Su

Doctoral Dissertations

The effects of the level and duration of feed restriction on the in vitro activities of hepatic drug metabolizing enzyme system were examined in male weanling Sprague Dawley rats fed ad libitum or feed restricted at 15%, 30% and 45% for a period of one to five weeks (Experiment I). Increasing levels and duration of feed restriction resulted in significant progressive increases in hepatic microsomal protein, cytochrome P-450 content and the in vitro activities of microsomal aniline hydroxylase. p-chloro-methly-aniline(PCMA)N- demethylase and p-nitrophenol UDP-glucuronyl transferase activities were unaltered by the feed restriction while cytochrome c reductase activity was significantly decreased. In …

Predictors Of Life Satisfaction Among Young Adults From Low-Income, Rural Areas Of Southern Appalachia, Stephan Maxwell Wilson

Doctoral Dissertations

A person's quality of life has been assumed by some researchers to be related to material and achieved status or to the material conditions of life by other researchers. Individuals' perception of the quality of their lives, however, is an experience of satisfaction. Therefore, researchers have begun to examine how individuals perceive the quality of their lives based upon individuals' internal comparisons of their own expectations and aspirations (i.e., internal referents) as predictors of life satisfaction. These internal referents may not be tied to mainstream American standards or values. Most life satisfaction studies, to date, have concentrated on middle-class, urban …

Effects Of Cadmium, Calcium, Age And Parity On Bone Mineral, Density And Strength In Female Rats, Beverley F. Hammond

Doctoral Dissertations

Weanling female rats were fed diets containing one of three levels of Ca (0.3, 0.6 or 0.9%) and one of four levels of Cd (0, 1, 5 or 10 ppm) in the drinking water. One half of each group was bred first as adolescents (55 days) and the other half as mature (110 days) females. Approximately 10 animals from each group were sacrificed after the first pregnancy and the remaining animals after the fourth pregnancy. Reproductive performance, plasma and bone Ca and P and bone density and strength were measured.

After the first pregnancy, offspring of dams treated with 5 …

Learning Style Preferences For Design And Their Relationship To Standardized Test Results, Roger H. Siles

Doctoral Dissertations

Statement of the Problem: The emergence of the proficiency testing movement has created a situation in which schools must administer these tests in a setting most conducive to student success. Students' performance on tests depends not only on their knowledge and skills, but also on conditions under which tests are taken. "Conditions of test administration affect test performance and hence test reliability by having differing effects on different test takers."

Recent research in the area of student learning style indicates that the various environmental elements of sound, light, temperature, and design affect student learning and test performance. This research indicates …

A Study Of Fine Structure Development Of Poly(Ethylene Terephthalate) In High Speed Spinning By Using A Pneumatic Drawdown Device, Chi-Chung Bai

Doctoral Dissertations

High speed melt spinning of linear, branched, and high molecular weight poly(ethylene terephthalate) (PET) polymers using a pneumatic drawdown device was carried out in this study. Characterization of the structure of final spun fibers of each polymer and the structure development along the spinline for different mass throughputs and take-up velocities were studied.

The final spun fibers were characterized with various techniques: birefringence, density, wide angle x-ray scattering (WAXS), differential scanning calorimetry (DSC), shrinkage, and tensile testing. A filament cutting technique was utilized and on-line temperature and birefringence measurements were performed to study the PET structure development along the spinline. …
